I've come to fix a leak under your sink... this is my first job on my own so I might be a litle slow.. though the boss says I do a cracking job.

I'm in and out from under the sink, standing up and down, the more I'm moving the more unknowingly my pants are revealing my ass crack more and more.. at one point I pull just my thong up, but nearly my whole ass is hanging out by the end.. no wonder you're standing around watching me so much.
